GLASS SURFACE MOUNT 0.5 WATT
ZENERS
DESCRIPTION
APPEARANCE
The 1N4678UR thru 1N4717UR series of 0.5 watt glass surface mount
DO-213AA Zener voltage regulators provides selection from 1.8 to 43 volts
in standard 5% tolerances as well as tighter tolerances at a very low test
current of 50 A. These are also available with an internal-metallurgical-
bond option by adding a “-1” suffix (see separate data sheet) including
military upgrade screening options. Microsemi also offers numerous other
Zener products to meet higher and lower power applications.
DO-213AA
